Description
技术领域technical field
本实用新型属于预制大节段钢箱梁的吊装施工技术，具体的涉及一种提供大节段钢箱梁吊装用的吊耳。The utility model belongs to the hoisting construction technology of a prefabricated large section steel box girder, in particular to a lifting lug for hoisting a large section steel box girder.
背景技术Background technique
随着建筑工业和技术的日益发展，我国已经在沿海进行了多个海上高架桥梁的施工。为了实现高效率和高性能的高架梁施工，现有高架路桥普遍采用具有较大跨度的大节段钢箱梁，其长度已经达到80至130多米，重量高达2000多吨。由于大节段钢箱梁的长度、体积及重量均过于庞大，一般通过在钢箱梁上分布设置多组吊点群的方式进行钢箱梁的吊装施工。虽然采用多达数十个吊点的方式对钢箱梁进行吊装，其每个吊点所承受的重量依然很大，因此需要设计一种满足吊装要求的吊耳。With the development of construction industry and technology, our country has carried out the construction of many sea viaducts along the coast. In order to achieve high-efficiency and high-performance viaduct construction, existing viaducts generally use large-span steel box girders with a length of 80 to 130 meters and a weight of over 2,000 tons. Since the length, volume and weight of the large-segment steel box girder are too large, the hoisting construction of the steel box girder is generally carried out by distributing multiple sets of lifting point groups on the steel box girder. Although dozens of lifting points are used to hoist the steel box girder, each lifting point bears a heavy weight, so it is necessary to design a lifting lug that meets the lifting requirements.

具体的讲，所述耳板的板面具有加厚部，该加厚部的中央开设耳孔；所述加厚部为耳板两端面焊接设置的加厚板。Specifically, the plate surface of the ear plate has a thickened portion, and an ear hole is opened in the center of the thickened portion; the thickened portion is a thickened plate welded on both ends of the ear plate.
一实施方式中，所述耳板的两端面下部分布设置加强肋板，所述加强肋板具有一平面弯折主体，该加强肋板的一侧面焊接连接耳板，加强肋板的下部焊接连接基板。In one embodiment, reinforcing ribs are arranged on the lower parts of both ends of the lugs, the reinforcing ribs have a plane bent body, one side of the reinforcing ribs is welded to the lugs, and the lower part of the reinforcing ribs is welded to substrate.
一实施方式中，所述加强肋板垂直于所述耳板和基板设置。In one embodiment, the reinforcing ribs are arranged perpendicular to the ear plates and the base plate.
另一实施方式中，所述加强肋板为六个，于耳板的两端面对称分别设置三个。In another embodiment, there are six reinforcing ribs, three of which are arranged symmetrically on both ends of the ear plates.
再一实施方式中，所述基板上开设有与钢箱梁的端面间连接固定用的固定孔。In still another embodiment, the base plate is provided with fixing holes for connection and fixing with the end faces of the steel box girder.
该大节段钢箱梁的吊耳采用较为简洁的钢构件制备，基板是与钢箱梁的端面进行连接的部件，其可以通过螺栓连接的方式进行固定。基板上竖立的耳板上形成有吊装连接用的耳孔，为了提高耳孔的牢固性和强度，本实用新型采用在耳板上焊装或连接加厚板的方式实现，耳孔外周的耳板均具有该加厚板，耳孔的承载性能大幅度提高。耳板与基板间采用多个加强肋板进行对称加固。平面弯折主体的加强肋板与耳板和基板间为断点焊接。加强肋板能够借助其平面弯折主体来消除耳板受力产生的部分形变，保持其加强性能。The lugs of the large-segment steel box girder are made of relatively simple steel components, and the base plate is a part connected with the end face of the steel box girder, which can be fixed by bolt connection. Ear holes for hoisting and connection are formed on the ear plates erected on the base plate. In order to improve the firmness and strength of the ear holes, the utility model is realized by welding or connecting thickened plates on the ear plates. The ear plates around the ear holes all have With the thickened plate, the load-bearing performance of the ear hole is greatly improved. A plurality of reinforcing ribs are used for symmetrical reinforcement between the lug plate and the base plate. The reinforcing ribs of the plane bending main body are welded at breakpoints with the ear plates and the base plate. The reinforcing ribs can eliminate part of the deformation caused by the stress on the ear plate by means of its plane bending main body, and maintain its reinforcing performance.
本实用新型的有益效果在于，该大节段钢箱梁的吊耳结构设计合理、牢固可靠，其能够提供较为牢固稳定的吊装承载，并具备良好的安全性。同时该吊耳与钢箱梁之间的施工安装方便，安装效率高。The beneficial effect of the utility model lies in that the design of the lug structure of the large-section steel box girder is reasonable, firm and reliable, which can provide relatively firm and stable hoisting and load bearing, and has good safety.
